2013年北京市延庆县农村生活饮用水水质监测结果

目的了解北京市延庆县农村饮用水水质现状，为农村生活饮用水管理提供科学依据。方法依据《2009年北京农村饮水水质卫生监测技术方案》在全县范围内随机选取65个集中式供水点，分别在枯水期、丰水期采集出厂水和末梢水进行水质监测。结果影响延庆县农村饮用水水质的因素为微生物指标，枯水期水质合格率为33．3％，丰水期水质合格率为29．6％，差异无统计学意义（χ2=0．17，P〉0．05）。出厂水、末梢水合格率均为31．5％。枯水期出厂水合格率为29．6％，末梢水合格率为37．0％，差异无统计学意义（χ2=0．33，P〉0．05）。丰水期出厂水合格率为33．3％，末梢水合格率为25．9％，差异无统计学意义（χ2=0．36，P〉0．05）。枯水期、丰水期微生物指标合格率均为33．3％。结论延庆县农村饮用水卫生状况不容乐观，需进一步完善农村改水和对饮用水的消毒工作，有关部门应加强宣传和监测力度。

Monitoring results of rural drinking water quality in Yanqing County of Beijing in 2013

Objective] To understand the current status of rural drinking water quality in Yanqing County of Beijing, provide scientific basis for management of rural drinking water. Methods ] According to ＂Technical Proposal of Rural Drinking Water Quality Hygiene Monitoring in Beijing in 2009＂, 65 centralized water supply sites were randomly selected. The samples of finished water and tap water were collected in dry season and wet season, and the water quality was monitored. Results ] The influencing factor of rural drinking water quality in Yanqing County was microbial indicators. The qualified rates of water quality in dry season and wet season were 33.3 % and 29.6% respectively, and the difference was not statistically significant （ ~2 = 0.17, P 〉 0.05 ）. The qual- ified rates of finished water and tap water were 31.5%. The qualified rates of finished water and tap water in dry season were 29. 6% and 37.0%, and the difference was not statistically significant （ χ2 = 0.33, P 〉 0.05 ）. The qualified rates of finished water and tap water in wet season were 33. 3% and 25.9%, and the difference was not statistically significant （ χ2 = 0. 36, P 〉0.05）. The qualified rates of microbiological in dry season and wet season were 33.3%. Conclusion] The sanitary status of rural drinking water in Yanqing County is not optimistic, we should further improve the water and disinfection work of drinking water.
